'Cedar Rapids, in the county of Linn and State of VIowa, have invented certain new [and useful Improvements in Acetylene-Gas (frenerators,V of which the following is a specification.

This invention relates to improvements in acetylene gas generators, and has for one of its ob]ects to provide a 'simply constructed apparatus of this character which may be 'installed externally 'of u building'and in po-l sition'to-'be protected from the frost Where. by alldan'ger of the escape of gas is avoided.-

Another object ofthe invention'is to provide a device of this character which is :1utoma'tie v-inits operation7 sothat the as is generated, only so fast as used 'an amount generated increased with any in'- crease in demand.

Another object of the invention isA to provide a device ofthis characterwhich is readily accessible fdr inspection or repairs,

or for charging with a fresh supply of" carbid.

Another object of the inventmn 1s to pro- ;v vi'de a device .0 thi s 'chatacter wherein Another object of. the invention is-ito. pro.

.Another object of the invention to prei vide a' device of this character'having-means. for removing surplus moisture from the. gas

prior toits passage to a purien Another object ofthe invention is-'to pro. vide a device 'of this character having meansV for internaland external condensation and' ivitha purifier located' between the two condensingdevies. i

gas to freely pass into the asometer bell.

Mounted upon the'mem er 12 is a 'carbid holder, represented as a whole at 16', and

i refers-bly formed with a hopper Sha ed ottom 17 and a-do'wnwardly facing ischar e opening -18 at the 4bottoni-of the..h0p

per ike portion. The member 16 is also provided with afillin openin covered by a suitable cap 19, pre erablyjt readed, and provided with a suitable packing.

21 is likewise connected tothe gasome'te-r to permit the gas .to be blown oil when required.

Extending through the holder 16 .is a tubular bearing 22, through which a vertical shaft 23 extendsand is mounted for rotation u the holder. At its upper end the shaft 23 is provided with a bevel pinion 24 and-provided with a valve 25 at its lower en d'oper-j ating to close the discharge 18 of the holder when in-one position 'and to open the dis-r cliargev whenin another position.

.Mounted for oscillation upon: the' holder,4

is a gear segment 26 in constant engagement with the "pinion 24. and provided with a' weight 27 at oneend and a bearing roller' 28 atthe other end. The weight 27 of the 'gear 27 maintains the valve 25 in closed posit-ien,

and cuts off any flow of theearbid. When segment operates' to maintain thesegm'e'nt normally in one position with the valve 25 closed, and when in this position the roller 28 is in its highest position and adapted to.

be engaged by the top of the gasometer 14 wlien'the latter descends to a' point nea-rits lowest position. By this simple arrangement when a sufficient quantity of gas has been.-

generated to elevate, the bell 14 the weight the consumptionof the carbid reducesthe quantity to a certain predetermined amount the descent of. -the bell caused, by the'consumption of the-gas will engage' the roller 28 and oscillate lthe segment 26 with the result of. correspondingly oscillating the shaft 23` and opening the valve 25 and permitting a quantity of the carbid to fall into the water below, the latter being indicated at 29. This results in the generation of afresh supply of gas which, rising through the ori ices 15, fills 'the bell 14 and again elevates theA latter-and thus releases the segment 26 and permits the weight 27 to again close the valve 25 and automatically cut 'oif 'th further supply of carbid. .The improvedapparatus is thus automatic in its action,

and the lgas is generated only so fast as required, r as fast as itis consumed.

Located within the generating chamber,

or' internally ofthe member 12, is a cylindrical -member 430 having a downwardly directed inlet 31- and connected at 32 with 'the main service .pipe 33. The member() is filled with a suitable' urifyin material,

suchas hair, felt, or the ike, so t at the-gas is purified before its passage tothe service pipe. At'the lower end of the service pipe an extension 34e is located and forms an outside condensing chamberl to receive any moisture which. resultsl from the condensation-.of the moisture in the gas or the.A

sweating fof the pipe'. By this means a "double condensing action takes place and thereby' materially increases the efficiency The gasometer 14 is provided with, suitable lifting-handles 20, and a discharge valve and utility of the improved apparatus.

Theservice pipe 33 is conducted into the building to -be lighted, referably beneath the ground as indicated? and is provided 4With a screw cap which may be removed 'to provide access to the pipe toV enable surplus -water to be removed, and4 prevent ooding ofthe service pipe. y The. improved device is simple in construction, can be inexpensively manufactured o f any suitable material, but will preferably be of'sheet steel throughout, and also preferably galvanized or otherwise treated to preve'nt corrosion."

Located within dischar e 18, is a conical detlector 36 tohold the cargid back and prevent itrom clogging and thus checking the discharge. The lower end of the shaft 23 is :threaded and supplied with binding nuts 37 by which the valve 25 is `adjustably coupled to the shaft.-

-Depending from the conical bottom 17 of the holder is a cylindrical shield 39 which serves to protect the valve 25 when the carbid holder is removed.

The combination with a generating tank .and a gasometer, of a carbid holder having a dischar e opening, a rotating shaft, a valve connecte to said shaftiand operating as a movable' closure to said holder opening, a gearinion carried by' said shaft, and a wei hte an extending at one en into the ath' of saidgasometer and maintaining said valve normally closed and operated by the asometer when the latter moves downward y.
